Science Class Connect Rules

1. Science Class Connect Rules • Respect the classroom and our privileges • Do not pollute the chat box • Stay on topic • Science class connects are not free chat sessions • Respect the teacher and your peers • Be appropriate and use good language • Be kind to others • Class connects are a time to learn • Have fun! • Science is cool and full of lots of fun lessons and labs! If you are unable to follow these three rules your privileges will be taken away!

4. What is a weather front? A weather front is the boundary between two different types of air masses (different temperatures and humidity)

5. Warm Fronts If warm or more humid air presses forward and colder or drier air draws back, the boundary is called a warm front. **Warm fronts bring clouds and precipitation**

6. Cold Fronts If colder or drier air presses forward and warmer or more humid air draws back, the boundary is called a cold front. **Cold fronts bring storms and large thunderclouds**

7. Stationary Fronts When a cold air mass and a warm air mass meet but are at a standstill, the boundary is called a stationary front. **Stationary fronts bring gray skies, rain, or snowy weather that may last a long time **

8. Occluded Fronts Sometimes a warm air mass can get caught between two cold fronts which can force the warm air up into a wedge shape which is called an occluded front. **Occluded fronts bring gray skies, rain, or snowy weather that may last a long time **

9. Warm Front Cold Front Stationary Front Occluded Front Warm, less-dense air rises gradually above cooler air Rainy or snowy weather lasts a very long time at this front Denser, colder air pushes in under warm air Weather may be drizzly or snowy Cold and warm air are next to each other, but are at a standstill Warm air is forced up in a wedge between two masses of cold air This kind of air mass usually brings thunderclouds and storms

Warm Front Cold Front Stationary Front Occluded Front Warm Front Warm, less-dense air rises gradually above cooler air Rainy or snowy weather lasts a very long time at this front Denser, colder air pushes in under warm air Weather may be drizzly or snowy Cold and warm air are next to each other, but are at a standstill Warm air is forced up in a wedge between two masses of cold air This kind of air mass usually brings thunderclouds and storms
